FLVY- FAN.

SPECIFIGATIQN forming lowingis a full, clear, and exact description, 7

reference being had to the annexed drawings, forming part of thisspecification.

This invention relates to fly-fans in which an oscillating or a rotatingarm is provided with a brush or similar device which is to be movedthrough the air; and theinvention has for its object to secure anincreased movement of such brushing device without employing othermechanism for driving it than the movement of the arm.

In the drawings, Figure 1 is an elevation of a fly-fan having two arms,which are adapted to be rotated by clock-work, showing my improvement.Fig. 2 is a side elevation of a hand fly-fan embodying myimprovement,and

Figs. 3, 4, 5, and 6 are detail views showing modifications.

A indicates a stand, which is to contain a clock mechanism for rotatingavertical shaft, B, which is provided with arms 0, having flexiblejoints D. At the outer ends of the arms are provided axles E, on whichare mounted wind-wheels F, adapted to be rotated by the-action of theair on the blades G as the arms are made. to revolve by the clockwork.

The wind-wheel F is preferably formed of a series of clamps, H,supported on a hub, ring, or disk, and flexible blades G, made of paperor other suitable material, which are held in position by the'clamps. Asshown in Fig. 2, the clamps may be arranged in one and the same plane,so as to hold the blades in such plane, to the end that the latter maybedeflected to either side'of said plane by the oscillation of the wheelthrough the air in the direction of its axis. This construction adaptsthe wheel for use in a hand fiy-fan, the movement of the arm I to andfro through the air serving to rotate the wheel continuously in onedirection.

work, it is unimportant that the blades should be of flexible characterif the clamps are set obliquely, as shown in Fig. 1, and the. windwheels intended for such use may be formed with the clamps so arranged,or made adjustable, so as to be set in such position when desired. Theonly advantage of setting the clainps obliquely with respect to theplane of the wheel is that nov additional force will be required fordeflecting the blades in such case, and the wheels may beorotated with.a very slow movement of the arms. In a hand brush or fan a more rapidand forcible movement may be given to the arm carrying the wheel, and insuch case the wheel having the blades set in oneand the same plane isindispensable where a continuous movement is desired.

I do not confine myself to either of the special forms of wheels abovedescribed, since the construction may be varied at will, as shown inFigs. 3, 4, 5, and 6, without losing any of the advantages set forth.

The clamps are preferably formed by doubling a strip of soft metal uponitself, and the metal may be struck up, as shown at J, to form a recessfor accommodating a fold of the paper blade, to prevent the latter fromcoming out accidentally.

The blades may be perforated or cut away to lessen the degree ofresistance to the air.

What I claim is 1. The combination, with the arm of a fan or brush, of awind-wh eel h avin g blades of flexible material set in one and the sameplane, whereby the blades maybe deflected to either side of said plane,according to themovement of the arm, substantially as and for thepurpose specified'.

2. The combination, with the arm of a fan or brush, of a wind-wheelhaving a-series oi clamps, and blades formed of strips of flexiblematerial secured by the clamps, substantially as shown and described.
